You are in a boat in arctic sea, surrounded by floating icebergs that drown you if they touch you. You have two possibilities to avoid them: You can drive the boat to avoid them and shooting at these to destroy them. To drive the boat needs some practice. Use the space bar to go forward and the left and right arrow keys to turn. You also have a boost mode by using the "delete" key. I would however not recommend it, because in this mode, the boat cannot be driven and you have no idea where it makes you go! To shoot, align the boat to the iceberg you want to destroy and press the "M" key. If you get it, it will be broken in smaller icebergs that are less dangerous. Have fun.
